Tonyan was limited in practice Wednesday due to a knee injury, Matt Schneidman of The Athletic reports.
Tonyan has had a muted start to the season, with four outings of two or fewer catches and no more than eight yards. His only somewhat productive outing came in Week 2 against the Lions, when he hauled in all three targets for 52 yards and one touchdown. There's been no indication Tonyan's knee issue is threatening his odds to play Sunday at Chicago, but the next two days of practice could shed light on how he's trending.
