Although it’s early on in the season, Cleveland Browns have been plagued by injury concerns and their star running back Kareem Hunt is the latest to join the growing list. During a 14-37 loss to Arizona Cardinals on Sunday, Hunt suffered an apparent serious calf injury.

After the game, the team announced that the 26-year-old is expected to miss at least one month because of a “significant” calf injury, according to Associated Press inputs.

Hunt recorded 66 yards on 14 carries while also gaining 12 yards on three receptions. However, he suffered a leg injury in the second half. The 26-year-old’s right leg buckled as he tried to walk off the field after a passing play. Trainers then assisted Hunt to the sideline and medical tent.

The Browns are also awaiting further tests on quarterback Baker Mayfield’s injured left shoulder, and they aren’t sure yet if he — or other starters, including running back Nick Chubb and receiver Odell Beckham Jr. — will be able to play Thursday night when Cleveland hosts the Denver Broncos.

“I’ll have a better sense tomorrow with a lot of these guys. I don’t know is the truth. I have to see how Baker and all these guys respond over the next 24 hours,” coach Kevin Stefanski said, AP reported.

Stefanski said that Hunt, who along with Chubb gives Cleveland one of the NFL’s best rushing attacks, will likely go on injured reserve, which means missing at least three games.

Stefanski said Hunt’s injury is more in the “ballpark” of four to six weeks.

The Browns (3-3) were already missing Chubb due to a calf injury, along with starting offensive tackles Jack Conklin and Jedrick Wills Jr., before Hunt went down without any contact on a passing play as Cleveland tried to rally.

Hunt had to be helped from the field and the sight of the hard-charging 26-year-old being carted to the locker room left a few teammates shaken.
