Programming note: For comprehensive 49ers-Seahawks coverage tune in to 49ers Central tonight at 6:30 on Comcast SportsNet Bay Area.
Seahawks receiver Percy Harvin was on the receiving end of a couple of hard hits courtesy of the New Orleans Saints defense, eventually knocking him out of last Saturday's game with concussion symptoms.
Harvin engaged in baseline testing on Monday, according to ProFootballTalk.com. The test compares his post-concussion cognitive abilities to results taken before his concussion.
It is unknown whether or not the fifth-year NFL receiver will be ready to go against the 49ers in Sunday's upcoming NFC Championship game in Seattle.
Harvin had three receptions for 21 yards in Saturday's playoff game against the Saints before leaving with a concussion.
