"He did great [in practice this week] and looked 100 percent and full speed the whole time," Carroll said after Friday’s practice. "He looks ready to go. I have no hesitations in saying that. He’s playing and doing everything we can ask him to do, every aspect of it."
That likely means Harvin will return kickoffs along with playing receiver.
Four players did not practice Friday -- receiver Doug Baldwin (hip pointer), linebacker K.J. Wright [foot], running back Marshawn Lynch [knee bruise] and cornerback Bryon Maxwell [neck]. All four are listed as probable for the Super Bowl.
"Actually, they’re more than probable," Carroll said. "They’re fine, and they’ll play."
Defensive tackle Brandon Mebane was limited in practice with a sore ankle, but Carroll said Mebane will be fine by next weekend.
