49ers forge ahead without Crabtree

SANTA CLARA, Calif. (AP) — Mike Singletary is sticking to the company line: San Francisco’s coach remains focused on the players who are in camp for the 49ers and isn’t busy worrying when top draft pick Michael Crabtree will end his holdout and finally show up for practice.

With one week of training camp already complete, each day the standout receiver from Texas Tech misses puts him further behind in learning a new offense and becoming familiar with his teammates.

“In terms of Crabtree, when he comes in, he comes in,” Singletary said Friday. “Would you love to have him in? Absolutely. You’d love to have him. Do we want him here? Yes, we want to have him in. But until that happens, I just can’t sit back and think about the what-ifs. All I can do is concentrate on what is, and control that.”

The Niners’ receiving corps took another hit to its depth chart with the loss of Brandon Jones for eight weeks because of a small fracture in his right shoulder. Jones, who underwent X-rays on Friday, was injured during Thursday’s late practice trying to make a diving catch while all alone in the end zone during 7-on-7 work.

Singletary still believes he has the depth at wideout to get by, for now at least. The team’s first exhibition game is next Friday night against the Denver Broncos.

San Francisco did add receiver Chris Francies on Friday, releasing defensive lineman Babatunde Oshinowo to make roster room.

With Jones’ injury and Crabtree’s absence — the sides apparently were far apart Friday — there’s an opportunity for Dominique Zeigler and Arnaz Battle to make the team and play a role.

A report surfaced Thursday that the 10th overall pick was prepared to sit out all season, re-enter the draft in 2010 and wait for the money he thinks he deserves — comparable to that of Oakland Raiders rookie Darrius Heyward-Bey, the seventh overall pick who last week signed a five-year contract that will guarantee him at least $23.5 million.
