Jonathan Martin SF 27 Days

Martin will start at right tackle if Anthony Davis (hamstring) can not suit up Sunday at Dallas, CSN Bay Area reports.

Martin showed promise in the preseason filling in for Davis while he recovered from offseason surgery. It secured him a backup spot on the 49ers' offensive line, and now it looks as if he will start week 1 with Anthony Davis (hamstring) looking doubtful.

ESPN 49ers reporter Bill Williamson believes San Francisco would turn to OT Jonathan Martin if G Alex Boon's holdout lingers into the season.

It is highly unlikely this situation develops, but if it does Williamson sees Martin as a more likely replacement for Boone than career-backup G Joe Looney. Martin has never played guard and is well behind after losing 12 pounds and missing three weeks of practice fighting a bout with mononucleosis. The 49ers' best-case scenario would be for Boone to report to camp.

49ers OT Jonathan Martin missed more than three weeks of practice due to a bout with mononucleosis.

After losing about 12 pounds due to the illness, Martin finally returned to the field on Monday. Still, missing any offseason work is not good for a player on the roster bubble whose desire to play football has been questioned. Martin, who was at the center of Miami's Bullygate scandal last year, did say that the 49ers' locker room is a "great environment" where players take care of each other.

Updating an earlier item, the 49ers acquired OT Jonathan Martin for a conditional seventh-round pick in 2015.

The condition is that Martin must make the 49ers' 53-man roster. It means the Dolphins will receive no compensation if Martin doesn't make the team. Martin is the favorite for swing-tackle duties, but is far from a lock to earn a spot.

49ers acquired OT Jonathan Martin from the Dolphins for a conditional draft pick.

The conditional pick is almost certainly a day-three selection. It's possible the Dolphins could end up with no compensation if Martin doesn't make the 49ers' 53-man roster, but that's just speculation. Martin had been on a leave of absence from the Dolphins since Week 9. A 2012 second-rounder, Martin hasn't looked like he can cut it at the NFL level, but was miscast as a left tackle last season. Reuniting with college coach Jim Harbaugh should be a boon for his confidence, and perhaps his game. He'll fight for swing-tackle duties in camp.

Andrew Luck said he would 100 percent be in favor of the Colts acquiring Dolphins OT Jonathan Martin.

"I'd say I love Jon, we had a great time at Stanford together, still stay in touch with him regularly and I think he's a great man," Luck said. The Stanford connection is a deep one in Indianapolis. In addition to Luck, OC Pep Hamilton, WR Griff Whalen and TE Coby Fleener all were part of the Cardinal with Martin. It doesn't hurt that the Colts are in serious need of offensive line help.

Dolphins owner Stephen Ross expects to meet with Jonathan Martin "soon."

Martin is universally considered done with the Dolphins, but Ross still wants to meet with him face-to-face before releasing or trading him. "I haven't heard what his feelings are," Ross said, somewhat incredibly. "I think I've read the report. I think he wants to talk to me as much as I'm prepared to listen. When you've dealt with something, it's nice to understand it a little bit more by hearing from the person directly." The meeting will be perfunctory. Martin is done in Miami.

During a meeting with coach Joe Phibin, GM Dennis Hickey and CEO Dawn Apante, Jonathan Martin's representation conveyed to the Dolphins that Martin isn't comfortable returning to Miami.

A source informed the Boston Globe that Jonathan Martin has a "zero percent chance" of ever playing for the Dolphins again.

The Globe's Ben Volin was a former Dolphins beat writer, so he has connections in Miami. Martin has burned too many bridges inside the Dolphins' locker room and has played a role in head trainer Kevin O'Neill and OL coach Jim Turner losing their jobs. Martin should be able to get a look-see from another club, though the aforementioned source doubts it. He's still under contract.

The Dolphins plan to huddle with Jonathan Martin's "camp" as soon as next week's Scouting Combine.

Per FOX Sports' Mike Garafolo, Martin "wants to play" football in 2014, and has yet to request a trade. The trade demand may occur in Indy, especially with OL coach Jim Turner still in the Dolphins' employ. The most likely landing spot at this point for Martin appears to be San Francisco, where coach Jim Harbaugh knows Martin well from Stanford and supported him in the Wells Report.
