Longtime Rams offensive lineman Rob Havenstein has announced his retirement, doing so via his Instagram Tuesday afternoon.

“11 years, 150+ starts, 4 time captain, 4 NFC West Championships, 2 NFC Championships and 1x Super Bowl Champion. What a ride it’s been! I can look back on my career and smile knowing I have given everything I had and more to the game I love,” he wrote on Instagram. “In saying that, I am officially retiring from the NFL.”
