Mike Glennon might attract a large contract from some quarterback-needy team, but a league source said Tuesday morning it will not be from the 49ers.
The 49ers have no interest in signing Glennon to take over as quarterback, a league source told CSNBayArea.com. The 49ers had been reported as one of the teams that might pursue the Tampa Bay Buccaneers backup quarterback.
Glennon, 27, has attempted just 11 passes the past two seasons as Jameis Winston’s backup. In 2013 and ’14, he started 18 games. The Buccaneers were 5-13 in those games. Tampa Bay selected Winston with the No. 1 overall pick in the 2015 draft.
In his career, Glennon has completed 59.4 of his 374 pass attempts for 4,100 yards with 30 touchdowns, 15 interceptions and a passer rating of 84.6.
The 52-hour open-negotiating period began for scheduled free agents on Tuesday at 9 a.m. Teams are allowed to enter into negotiations with the agents of free agents, but contracts are not allowed to be signed until Thursday at 1 p.m.
The 49ers do not have any quarterbacks under contract for the 2017 season. Colin Kaepernick opted out of his contract to become an unrestricted free agent, along with Blaine Gabbert, Christian Ponder and Thad Lewis.
The 49ers on Wednesday were assigned outside linebacker Cassius Marsh off waivers from the New England Patriots.
The Patriots waived Marsh on Tuesday after acquiring him in September from the Seattle Seahawks in exchange for fifth- and seventh-round draft picks.
Marsh (6 foot 4, 245 pounds) appeared in 46 games in his four NFL seasons. Three of his four career sacks came in 2016 while with the Seahawks. He was Seattle's fourth-round pick in 2014.
Marsh is the second defensive player the 49ers have claimed off waivers this week. The club acquired former Jacksonville Jaguars defensive lineman Sheldon Day on Monday. The 49ers released defensive linemen Tony McDaniel and Datone Jones within the past week.
The 49ers are at their roster maximum of 53 players. The club will have to clear a roster spot if Tank Carradine, as expected, is activated off injured reserve in order to play Sunday against the Seattle Seahawks at Levi’s Stadium.
SANTA CLARA – Quarterback C.J. Beathard is expected to make his fifth consecutive start for the 49ers on Sunday, but Seattle coach Pete Carroll said his team will be prepared to face Jimmy Garoppolo, too.
“It really isn’t a factor,” Carroll said in a conference call with Bay Area reporters on Wednesday. “We’re just preparing for the 49ers. They got a style of offense. They got really good players who do what they do. And whoever’s triggering it from the quarterback spot, we’re going to go play football.
“We’ve seen Jimmy play. We’ve seen how he’s mobile and the kind of athlete and competitor he is. But other than that, we just go play football. We can’t do anything about that.”
Beathard remained on the sideline when the clubs met Sept. 17 in Seattle. The Seahawks have defeated the 49ers seven consecutive times, including a 12-9 victory in Week 2 this season. Quarterback Brian Hoyer started the 49ers’ first six games of the season and rushed for just 7 yards during that time. Beathard has 115 yards rushing on 20 attempts in Kyle Shanahan’s offense.
“He’s been mobile. He’s got a rushing average, you know,” Carroll said of Beathard. “He’s averaging 5-yards a carry and stuff. They’re incorporating him in the run game some that we have to be concerned about. That’s different than other quarterbacks at times. I’d think Jimmy can do the same stuff.
“He (Beathard) is getting more settled. You can see the offense growing. You can see Kyle able to expand and do more stuff. He’s an incredible offensive coordinator and play-caller that we’ve respected for a long time. I think they’re just grown and they’re getting more proficient at what they’re doing."
