The San Francisco 49ers were back at practice in front of the media today, which means a few tidbits here and there to be found. We've got overall reports from Matt Maiocco and Grant Cohn thus far, with more likely to show up in a bit. I'll add more as they appear. Fooch's Update: Cam Inman has an overall recap, a Jonathan Martin piece, and a Chris Cook piece. And we've got a 49ers.com recap. Chris Biderman has his recap.
One of the more notable pieces of news to come out of practice is the return of Jonathan Martin. The reserve lineman was dealing with mono, but is back at practice this week. According to Coach Harbaugh, Martin was also in attendance at Monday's practice. Thus far, he has been handling tackle work, but Jim Harbaugh said it was still possible he could get in guard work. Harbaugh told the media Martin had not yet done guard work.
At Tuesday's practice, it sounds like he split time at first string right tackle with Adam Snyder. Anthony Davis is sidelined while his shoulder gets back to 100 percent, opening the door for reserves to show a little something. The 49ers starting offensive line is mostly set, with Daniel Kilgore in the only significant starting competition. Snyder was the primary backup all along the line last season, but he faces serious competition from Martin, Joe Looney, and potentially even Marcus Martin.
Where this could also get interesting is at right guard. Alex Boone is the starter, but we have no idea if he will hold out from training camp. Matt Maiocco wrote recently about Boone's current agents, and how they have shown a history of holdouts with some of their more notable players. If Boone were to hold out into the season, suddenly the right guard position becomes wide open. Joe Looney and Adam Snyder would seem to be the primary competitors, but Jonathan Martin could still work his way into the mix, and Ryan Seymour did spend the final few weeks on the 49ers 53-man roster. What was a rock of stability becomes a big fat question mark if Boone holds out.
