Mario Manningham has said that he is taking his return from a lengthy knee injury "day-by-day".

The San Francisco 49ers wide receiver joined his teammates on the practice field yesterday for the first time since tearing knee ligaments during the NFC West side's penultimate regular season game of 2012.

The 27-year-old told the team's website: "Just taking it day-by-day, seeing how it goes. I'm not sure [when I'll play again], because I don't how I'm going to feel.

"If I feel good I might play. I'm not putting a time limit on there, just taking it serious day-by-day.

"I'm just doing what I've got to do to get back to 100[%]. Be patient, come back stronger. Every day you wake up, you have to think you're going to come back stronger than you left."

The 49ers face the Tennessee Titans this weekend.
