San Francisco coach Coach Mike Singletary informed reporters on Monday that there is a “strong possibility” Michael Crabtree will make his 49ers debut in Week 7 as a starter. After only one week of practice, Crabtree has supplanted incumbent starter Josh Morgan.

It’s a big surprise because Morgan is the run-first club’s best blocking wideout and second-leading receiver behind only tight end Vernon Davis. Isaac Bruce will stay at flanker. “They gave him my spot,” Morgan said Monday. Crabtree, who must’ve been highly impressive in bye-week practices, is still a rookie and will be an inconsistent member of the 49ers offense.

Elsewhere from around the NFL:

Carolina: The Panthers have acquired DT Tank Tyler from the Chiefs for a 2010 fifth-round draft pick. Tyler, who was a third-round pick in 2008, has only made two starts since the team switched to a 3-4 defense. The Carolina Panthers have a severely depleted defensive line and the acquisition of Tyler should help.

Dallas: Cowboys WR Miles Austin has overtaken Patrick Crayton to be the Cowboys’ starting flanker. The Cowboys depth chart has already been adjusted and Austin was practicing with the first-team offense at Monday’s practice. Any fantasy owners that are still holding on to Crayton should drop him immediately.

Seattle: Seattle Seahawks coach Jim Mora indicated on Monday that MLB Lofa Tatupu’s pectorals muscle tear is not necessarily season ending. Apparently, Tatupu only suffered a partial tear and the injury could be rehabbed without surgery.

Tennessee: Titans owner Bud Adams informed the Nashville Tennessean that he wants to see Vince Young play more going forward. “I have been wanting (Jeff Fisher) to play Vince Young more because (Kerry) Collins has been having his problems,” Adams said. “I just think we need to find out how well (Young) can do.” In the past, Adams has been a big fan and supporter of Young. He added that he’d have to “look at that pretty hard” if the Tennessee Titans “don’t look better” when asked about Fisher’s job security.

Atlanta: Falcons coach Mike Smith confirmed that LCB Brian Williams tore his ACL in Sunday’s win. He’ll be placed on injured reserve, ending his season. Smith, who was a reliable cover man and versed in Smith’s scheme, will be placed on injured reserve and his season is over. Williams was on a one-year deal and may not return in 2010 at age 31.

New York: The NY Daily News confirms multiple reports that Jets NT Kris Jenkins has a torn ACL. Jenkins, who will be 30 in 2010, will certainly be back with the Jets at an affordable $2.25M salary.

Baltimore: Ravens RB Ray Rice leads the NFL in yards from scrimmage through six games. “I’ll admit this: He’s probably a little more talented than maybe we even thought when we drafted him,” coach John Harbaugh said, also praising Rice’s football IQ. At this point, it appears that Rice is the clear featured back in Baltimore and should be starting in nearly every fantasy league.

Oakland: Raiders coach Tom Cable said Monday that Chaz Schilens (foot) will likely make his season debut in Week 7 against the Jets. Cable says the receiver rotation has not been set, but Schilens may as well play a major role right away as the Raiders get no production out of their WR core. Schilens’ fantasy value is being crushed by an underperforming Oakland offense.
