Minnesota Vikings star Justin Jefferson will undergo more testing on Monday after injuring his hamstring in Sunday's 27-20 loss to the Kansas City Chiefs Pro Football Talk's Myles Simmons.
Head coach Kevin O'Connell told reporters after the game it's "still very early" to try establishing a timeline for Jefferson's return.
The injury occurred in the fourth quarter when Jefferson was running a route and his leg slipped on the turf.
A similar play happened earlier in the game involving Chiefs tight end Travis Kelce, who left the game in the first half before returning in the third quarter with his ankle taped up.
