What It Means:

Walker didn't appear to be hindered during Sunday's win over the Detroit Lions, but may have tweaked something. He'll need to get at least a limited session in by the end of the week in order to have a chance of playing against the Oakland Raiders in Week 3. If he's forced to sit, it would create more looks for Tajae Sharpe and Rishard Matthews.

Among the 40 tight ends to see at least five targets this season, Walker ranks fifth in Reception Net Expected Points per target.
