SANTA CLARA, Calif. (AP) - San Francisco 49ers coach Jim Harbaugh has been sent to the hospital for a ``minor procedure'' after doctors discovered he had an irregular heartbeat.

The team said Harbaugh had the procedure done at Stanford Hospital on Thursday. The 49ers anticipate Harbaugh will be back at the team's facility Friday.

Special teams coordinator Brad Seely oversaw the 49ers practice.
