Shanahan: Pettis out against Rams, updates on Garçon and Taylor

San Francisco 49ers head coach Kyle Shanahan made a KNBR appearance on Friday morning and offered an update on the team’s receiving corps heading into Sunday’s match-up against the Los Angeles Rams.

Rookie receiver Dante Pettis, who’s missed the last four games after suffering a knee injury against the Los Angeles Chargers, has again been ruled out for Sunday. Pettis had been making progress and was a limited participant in Wednesday’s practice before sitting out Thursday.

Shanahan also offered updates on slot receiver Trent Taylor and veteran Pierre Garcon.

Taylor, after having offseason back surgery, has steadily increased his production within the offense, having his best game against the Cardinals in Week 5 to the tune of seven receptions for 61 yards and a touchdown. His momentum was halted when he missed the 49ers’ Week 6 match-up against the Green Bay Packers after dealing with back pain. Taylor is questionable for Sunday.

Garçon, dealing with lingering shoulder and knee issues, was labeled as questionable by Shanahan. The 49ers coach didn’t seem confident in the veteran’s status heading into the weekend after he was a DNP on Wednesday and limited on Thursday. Garçon netted four receptions on six targets for 37 yards in Week 6.

The 49ers look to only have four healthy receivers heading into Sunday - Marquise Goodwin, Kendrick Bourne, Victor Bolden Jr., and Richie James Jr. They could elect to promote Steven Dunbar from the practice squad, but they already have seven receivers on the 53-man roster. Goodwin burst back onto the scene against the Packers, totaling four receptions for 126 yards and two touchdowns. He’ll likely once again be quarterback C.J. Beathard’s top receiving target against the Rams.
