Seven workouts has not yet produced an addition to San Francisco’s quarterback room, and one may not be coming despite the new 49ers backup being a former UDFA only promoted to the active roster this week. The 49ers do not plan to sign a veteran quarterback this week, NFL.com’s Jim Trotter tweets. While he adds that remains a possibility in the near future, don’t expect an outside addition to come this week. E.J. Manuel, Tom Savage, Kellen Clemens, T.J. Yates, Landry Jones, Matt Simms and Kyle Allen all worked out for the 49ers. But the NFC’s Bay Area team is evidently set with a C.J. Beathard–Nick Mullens depth chart heading into its Week 4 clash with the Chargers. The 49ers’ chances of being a surprise playoff contender absorbed a massive blow last week when Jimmy Garoppolo went down, and Kyle Shanahan said any veteran added would not be a threat to usurp Beathard. The second-year Iowa product started five games last season, completing 54.9 percent of his passes and throwing four touchdown passes compared to six interceptions. The 49ers went 1-4 in those games.

Here’s the latest from the NFC:

• The Cowboys‘ defensive fortunes have generally taken hits when Sean Lee isn’t available, and the linebacker’s latest absence comes at a bad time for the 1-2 team. Dallas will be without its top linebacker for a few weeks “at least,” Ian Rapoport of NFL.com reports (on Twitter). Lee suffered a hamstring injury on Sunday. This latest setback involves Lee’s right hamstring. A left hamstring issue caused him to miss time last season. First-round pick Leighton Vander Esch now stands to see a more prominent role in the near future.
• Dallas remains the favorite to acquire Earl Thomas, in the event the Seahawks trade him, Terez Paylor of Yahoo.com writes. Thomas drew a penalty for bowing at the Cowboys’ bench following an interception in Seattle’s Week 3 win over Dallas. The Cowboys have offered a second-round pick for Thomas, but the Seahawks still want more. The safety nonetheless heard more rumblings about a deal with Dallas on Sunday, though. “Yeah, of course, I heard chatter. People were coming up to me and saying a trade might happen,” Thomas said. “Even pregame, a couple Cowboys coaches came up to me, I don’t know if they were playing psychological games, but they were like, ‘You ready for the trade tomorrow?” He remains a Seahawk, but the situation’s become quite strange.
• Thomas said after Seattle’s win he missed two practices last week to protect himself from injury, and he expects to be fined for the absences. This is consistent with a report that emerged pregame Sunday. “I need to make sure my body is 100,” he said, via Brady Henderson of ESPN.com. “I’m invested in myself. If they was invested in me, I would be out there practicing. But if I feel like anything — I don’t give a damn if it’s small, I’ve got a headache — I’m not practicing. But I don’t want that to be taken the wrong way. I know I’m going to get fined. But that’s just where I’m at with that.” Pete Carroll said the Seahawks still “love” Thomas as a person and a player and described communication between the team and the All-Pro safety as “ongoing.” Carroll did not specify if this communication is regarding an extension.
• The Packers are preparing to start Byron Bell at right guard on Sunday against the Bills, Rob Demovsky of ESPN.com notes. Justin McCray is dealing with a shoulder injury, one the Packers don’t believe will be a long-term issue. However, Bell is expected to step in for the time being. An eighth-year player, Bell’s spent almost the entirety of his career at tackle. He has previously played guard but hasn’t worked there nearly as much as he has on the edge.
