Vikings WR Jordan Addison injures ankle, likely to rest Thursday

Minnesota Vikings receiver Jordan Addison suffered an ankle injury Wednesday during the team's joint practices with the Cleveland Browns , coach Kevin O'Connell said Wednesday, but the injury was not initially considered to be serious.

Addison suffered the injury after jumping and trying to make a contested catch during drills on the first day of the teams' pair of scheduled practices. He was eventually taken off the field on a cart. O'Connell said after practice that Addison was unlikely to participate Thursday but isn't expected to be sidelined for a long period of time.

Addison's departure from practice came shortly after O'Connell confirmed that rookie quarterback J.J. McCarthy will miss his entire rookie season because of a torn meniscus in his right knee, the latest in a series of injuries and tragic events that have marred the Vikings' summer.

Rookie cornerback Khyree Jackson was killed in a July 6 car accident . Second-year cornerback Mekhi Blackmon suffered a torn ACL on the first day of training camp, and veteran cornerback Shaquill Griffin hasn't practiced since straining his hamstring on the second day of camp.

Tight end T.J. Hockenson , meanwhile, is continuing to recover from a torn ACL and MCL in his right knee and might start the season on injured reserve.
