John Michael Gyllenborg Injury: Spotted in warmups Saturday

Gyllenborg (undisclosed) was spotted in early warmups ahead of Saturday's game against Colorado, according to 7220Sports.

The presence of Gyllenborg in early warmups isn't definitive, but it's an encouraging sign. The tight end isn't wearing the sleeve he was sporting last week, too, so his chances of playing seem to be quite high in this Week 4 matchup.
