Giants starting C Shaun O'Hara was placed in a hard cast Thursday and is expected to miss the remainder of the preseason. O'Hara is suffering from left Achilles tendinitis and ankle swelling and he expects to keep the cast on for up to five days.
OLG Rich Seubert will start at center in Saturday's preseason game in Baltimore. Backup C Adam Koets will play as well.
O'Hara, a two-time Pro Bowler, has missed only one game in the past five seasons and hopes to be ready for the season opener against Carolina.
"It's just something I've been dealing with pretty much all through camp," he said.
