SANTA CLARA, Calif. (AP) — Coach Mike Singletary all but acknowledged the 49ers have filed tampering charges against the New York Jets regarding top San Francisco draft pick Michael Crabtree.

When asked Monday if the team had filed charges, Singletary said it’s a situation ‘‘the league is going to handle internally.’’

‘‘I’m not going to get into that. We’ll let that play out, the process,’’ Singletary said. ‘‘I’m not even going to go there. We’ll let the league handle that and go from there.’’

He didn’t elaborate or provide further details on the matter.

The 22-year-old Crabtree, selected No. 10 overall by the Niners in April’s draft, is the last draft pick not signed.
