Jim Harbaugh today said that wide receiver Mario Manningham, who is coming back from an ACL injury suffered in December, "looked really good" during Thursday's practice. Asked about the timetable for Manningham's return to the active roster, Harbaugh said he didn't have a "crystal ball" but said "it's going to be soon."
"It looks really good," Harbaugh said. "He had a very good day yesterday."
Aside from Anquan Boldin, the 49ers haven't received much production from their wide-receiving corps this season. Manningham, who signed a two-year contract with the team last season, served as a third-down receiver until he was injured but still finished second on the team to Michael Crabtree with 42 receptions.
The 49ers have an open roster spot after releasing receiver Chris Harper Thursday. (He was claimed today by the Packers). Harbaugh said the team would add someone to the 53-man roster on Saturday but would not reveal what that transaction would be. It's likely that one of two rookies, defensive linemen Mike Purcell or Quinton Dial, will be elevated to the active roster.
Nose tackle Glenn Dorsey practiced on a limited basis today but is listed as questionable on the injury report. "Did good," Harbaugh said of Dorsey. "We'll make that determination," he said when asked if Dorsey would play against the Titans.
Notes - Ahmad Brooks is dealing with a family situation in Virginia and has missed the team's last two practices. He'll join the 49ers in Nashville this weekend.
* Guard Alex Boone was fined $7,875 for striking Cardinals defensive lineman Alameda Ta'amu, who in turn, was fined $10,000 for kicking Boone in the fourth quarter of Sunday's game. Cardinals safety Tyrann Mathieu was fined $7,875 for grabbing running back Kendall Hunter after Hunter scored a touchdown and unnecessarily throwing him to the ground. Boldin, who came to Hunter's defense and who was penalized, was not fined.
Right tackle Anthony Davis was fined $15,750 for clipping a Cardinals defensive linemen. Davis was penalized at the time for the clip.
* Like Dorsey, Jon Baldwin (illness), Ray McDonald (biceps), Carlos Rogers (knee) and Justin Smith (shoulder) are listed as questionable. They are expected to play. Dorsey is the only 49er who is truly questionable for Sunday's game.
