SAN FRANCISCO (AP) — A Giants fan brutally beaten on opening day at Dodger Stadium is opening his eyes but remains in critical condition at San Francisco General Hospital.

Chief neurosurgeon Dr. Geoff Manley said Wednesday that 42-year-old Bryan Stow has been weaned off of one of five anti-seizure medications since arriving Monday from a Los Angeles hospital.

He says Stow’s brain also showed no seizure activity during 30 hours of continuous monitoring.

Manley says these developments are positive but he could not predict Stow’s chances for recovery.

He says the short-term goal is to remove Stow from the remaining medications to better assess damage to his brain.

Stow was targeted by two drunken Dodger fans while wearing a Giants jersey at the game March 31. No one has been arrested in the attack.
