Sources: Brown tendered by Dolphins

The Miami Dolphins placed the first-round tender on running back Ronnie Brown, according to NFL sources.

The price for his tender was 110 percent of last year's base salary, which comes out to $3.969 million. Any team can sign Brown to an offer sheet and Miami would have seven days to match or get a first-round pick in return.
