The Arizona Cardinals were back in pads for the first time this summer Tuesday, but with it came a few heated moments.Throughout their morning practice, multiple scrums broke out as players tried to separate opposing players. Linebacker Isaiah Simmons and wide receiver DeAndre Hopkins were in a heated back and forth throughout the day and even defensive end J.J. Watt was involved in an altercation.Off the field, wide receiver Marquise Hollywood Brown returned from the non-football injury list. The receiver was taken off the NFI list before practice started but didnt participate in any drills after jogging through a few routes in the walkthrough..Were just easing him back in, head coach Kliff Kingsbury said. We want to start him with the walkthroughs and Im hoping by the end of the week he can start some individual drills and Im gue sing Monday be full go.D.J. Humphries is still battling a stomach bug that has sidelined him for all of camp. The left tackle did not practice, but was on the field with the offensive line group.. Another offensive lineman who was absent was center Rodney Hudson. This was Hudson’s third straight absence from practice. Kingsbury said they want to be smart Masahiro Tanaka Jersey with Hudson, and ultimately have him healthy for Week 1. Also taking a vet day off was Markus Golden, who also took one last week.Kingsbury gave an update on tackle/guard Justin Murray who has been walking around with a boot on his foot due to an ankle injury. The team is hoping to have him back in two or three weeks.The lo s of Murray led the Cardinals to sign guard/tackle Rashaad Coward to the roster following a workout on Monday. Coward was on the field practicing in multiple drills. Arizona cut wide receiver Christian Blake to make room for Coward.Kyler Murray tested positive for Covid-19 on Sunday and mi sed his second practice, but he is still taking part in the team meetings through Zoom according to Kingsbury, who said he hopes to have the quarterback in practice by the end of the week.UPDATE: As has been widely speculated in advance, the Cardinals reported a visit with outside linebacker Takk McKinley (6-2, 260) Tuesday. A Austin Romine Jersey first-round pick of the Falcons in 2017 (26th overall), McKinley played four seasons with the Falcons and 2021 with the Browns after signing as an unrestricted free agent. He became a free agent in March.Scroll to ContinueIn 60 career games (27 starts), McKinley totaled 20 sacks and has only 7.0 combined in the last three seasons.Notes and observationsAfter cornerback Marco Wilson intercepted quarterback Colt McCoy on a short pa s to the flat, Simmons picked up the ball to celebrate. The celebration got under the skin of Hopkins who got in the linebacker’s face before eventually being separated.Not long afterward, tensions were raised again when Watt and right guard Will Hernandez had to be separated up after getting in each other’s faces. There were numerous offensive and defensive players surrounding the combatants.A third scrum broke out before practice came to an end. It seems that the pads just bring out feistine s in players, but the sentiment is that these fights are a waste of time.Not a fan of fighting , Kingsbury said. I dont like wasting the time on the reps . . . and then the young guys there at the Don Larsen Jersey end dont get their two-minute rep. We just got to be more mature and be able to handle the competition.James Conner is strong. Of course, everyone knows this but Conner showed it off during a one-on-one pa s protection drill against Zaven Collins. Collins attempted to spin away from Conner, but the running back stayed in front and stalled Collins’ momentum.Cornerback Byron Murphy Jr almost intercepted a pa s, but barely mi sed the ball. Murphy laid on the ground in disappointment before Watt came by to pump his chest and get him back up.Running back Eno Benjamin continues to have a really good training camp. Every time he gets the ball he seems to burst through the defensive line. Granted, camp is nowhere as physical as a game, but Benjamin’s talent is standing out.Linebacker Ezekiel Turner has been in a steady rotation with Collins, Nick Vigil and Tanner Vallejo as inside linebackers. Tuesday, Turner put it all out on the field running down pa s-catchers and making stops.Kicker Matt Prater tested out his leg, making a 64-yard Gary Sanchez Jersey field goal.In the final portion of practice, linebacker Dennis Gardeck looked impre sive rushing the pa ser. Opposite Victor Dimukeje, the two bull-rushed the lineman and would have had a sack in an actual game.On the sideline during a small break, Conner, Eno Benjamin and Antoine Wesley competed in a synchronized push-up competition. It looked like Conner came out on top.
