Jonathan Martin's early weeks with his new San Francisco 49ers teammates have been spent recovering from mononucleosis and regaining strength zapped by the viral infection.

Because he was contagious, Martin initially had to isolate himself for part of this month while sick. That has limited his on-field time during the team's offseason program, and he didn't practice during the voluntary organized team activity Wednesday.

Martin was traded from the Dolphins to the Niners in mid-March, providing him with a new start after his departure from Miami last October. He accused teammate Richie Incognito of bullying in a scandal that overshadowed the franchise's 8-8 season.

San Francisco quarterback Colin Kaepernick says he hopes a Miami investigation from April that names him will soon be over. He notes, "I did nothing wrong in that incident."
