MONTREAL -- The Montreal Impact threw a few surprises into their picks in Wednesday's Expansion Draft, selecting several marquee names, including Houston's Brian Ching and Philadelphia's Justin Mapp.

Ching has gone on the record to say he would not move to Montreal if picked. How that will play out remains to be seen, and Montreal coach Jesse Marsch said he is still open to various options.

Mapp was one of two high-profile Union players on offer, the other being Freddy Adu. On Tuesday, Marsch indicated that Adu was a possibility, but in the end, chose his teammate, who does not come with as high a salary and is more established in the league on the field.

Elsewhere, Marsch chose to bolster the backline, acquiring San Jose centerback Bobby Burling, Columbus left back Josh Gardner, Sporting KC left back Seth Sinovic, Vancouver right back Jeb Brovsky, and Chivas USA right back Zarek Valentin.

The selection of Colorado midfielder Sanna Nyassi provides some good speed on the flanks, and Real Salt Lake's Collen Warner is an up-and-coming attacking midfielder who showed flashes in 2011.

The final pick, Seattle right back James Riley, was shipped to Chivas USA immediately in exchange for forward Justin Braun and midfielder Gerson Mayen.
