Disgruntled wide receiver Mike Wallace will end his holdout and report to the Pittsburgh Steelers this weekend, sources told the Pittsburgh Post-Gazette on Tuesday. Wallace plans to sign his $2.7 million tender and return to the Steelers after Saturday's preseason game in Buffalo. ESPN NFL Insider Adam Shefter reported last week that Wallace was expected to report before the end of the preseason so he could be ready to play in the Sept. 9 season opener at Denver.
