Stocker was signed to the active roster Thursday, Craig Peters of the Vikings' official site reports.
EDGE Analysis
Stocker has been back and forth between the practice squad and active roster over the past few weeks. He appeared in the Vikings' Week 6 contest against Carolina playing 10 snaps on offense and in Week 8 against Dallas playing 16 offensive snaps. He has totaled one target and one reception for seven yards. With Ben Ellefson (foot/knee) placed on IR a week ago, it's likely Stocker will file in behind Tyler Conklin and Chris Herndon on the Vikings' tight end depth chart against the Ravens on Sunday.
