Tonyan, who was carted off the field during Wednesday's practice session, was diagnosed with back spasms, Alec Lewis of The Athletic reports.

EDGE Analysis

Tonyan was down on the field for an extended period of time before being carted off, per Lewis. It appears the tight end has avoided serious injury, though he may be held out of the next few practice sessions until medical staff get a better sense on the severity of the injury. With Tonyan and T.J. Hockenson (knee) both sidelined, Josh Oliver and Johnny Mundt should see some reps with the first-team offense during drills.
