ST. LOUIS (AP) — St. Louis Rams cornerback Janoris Jenkins returned for the first defensive series of the second half after injuring his right ankle late in the half against Seattle on Sunday.

Seahawks cornerback Tharold Simon also injured an ankle in the second quarter and his return was questionable. Simon made his NFL debut after missing all last season due to injury.

Jenkins was hurt assisting on the tackle after a 22-yard reception by Cooper Helfet. He was down on the field for several minutes with 1:41 to play and Seattle at the St. Louis 36.

Jenkins walked off the sideline for medical tests and was replaced by Marcus Roberson.
