The Cleveland Browns believe that tight end David Njoku could be dealing with a high ankle sprain, multiple media outlets reported Sunday night.

Njoku was injured with 10:37 left in the third quarter of Cleveland’s season-opening 33-17 loss to the visiting Dallas Cowboys on Sunday. The Browns listed him as questionable to return, but he never did.

After the game, Cleveland coach Kevin Stefanski had no update on Njoku’s status but said that the 28-year-old will be getting tests on Monday to determine the severity of his injury.

Multiple reports indicated that Njoku left the stadium wearing a boot on his right foot.

Njoku finished with four catches for a team-high 44 yards on Sunday.

Njoku was a first-time Pro Bowler last season, when he hauled in 81 receptions for 882 yards and six touchdowns in 16 games (all starts).

Jordan Akins is currently the only other tight end on the Browns’ depth chart.
