SANTA CLARA -- Randy Moss isn't the only one making a comeback after spending 2011 out of the NFL. So is Jeff Fisher, who coached Moss during the 2010 Tennessee Titans' 6-10 season.
Fisher returned this season to coach the St. Louis Rams, who bring a three-game losing streak into Sunday's game against Moss and the host 49ers.
"I had great respect for what Randy had accomplished throughout out his career, and I was very impressed with him in the short time there," Fisher recalled Wednesday on a conference call. "He was a tremendous teammate. He had a huge impact on our young receivers, with his work ethic, and how he practiced and how competitive he is."
In Moss' journeyman season of 2010, he bounced from the New England Patriots to the Minnesota Vikings to the Titans, where he tallied six catches for 80 yards in four games under Fisher.
Fisher figured correctly that Moss is a positive presence among the 49ers.
"Personally we all have felt an influence from Randy in terms of his practice habits and work ethic," 49ers coach Jim Harbaugh said. "He's just a good guy to be around in the locker room and practice field."
Aside from his 13 receptions for 235 yards and two touchdowns, Moss' willingness to block and share his vast knowledge have been well received. Quarterback Alex Smith called Moss a "great example" and cited Moss' attention to detail and endless curiosity about the 49ers' schemes.

Moss was not available for comment Wednesday during the local media's access period in the locker room.
Wide receiver A.J. Jenkins and running back LaMichael James, the 49ers' top picks, haven't cracked the game-day lineup because "we have 53 healthy guys and you can dress 46 on game days," Harbaugh said.
