Just an update to clarify the report from Nfl central, the signing isn't confirmed although it looks to be more likely he will sign. A matter of crossing the T's and dotting the eyes.
From the PG:
Wide receiver Steve Breaston, who played at Woodland Hills High School, visited the Steelers Thursday and took a physical. He became a free agent when Kansas City released him Feb. 19. There was no word on whether negotiations have begun to try to sign him. ... With Roethlisberger, Timmons and Brown's restructured contracts, the Steelers should be close to the $14 million they needed to erase from their salary cap by March 12 to be in compliance with the league. ... The Steelers were the only team to claim quarterback John Wilson, 27, off waivers from the Jacksonville Jaguars and he was awarded to them Thursday.
I read where Breaston said he wants a chance to start, he'll get that opportunity in camp if the report is accurate, probably third receiver on the depth chart.
