If the Capitals fail to make up any ground in the standings and push themselves closer to the playoffs, GM George McPhee will be looking at several moves before the April 3 deadline.
With Florida Panthers center Stephen Weiss now out for the season, Ribeiro should attract much more interest from teams in need of help up the middle.
Ribeiro, who is earning a prorated $5 million this season, owns a limited no-trade clause and has a list of 10 teams he will not accept a trade to, according to CapGeek.com.
The Anaheim Ducks, Chicago Blackhawks, Toronto Maple Leafs, Ottawa Senators, Detroit Red Wings and Vancouver Canucks are among the teams looking to add a top-two center to their roster.
Earlier today, the Capitals placed defenseman Roman Hamrlik on waivers.
It's believed Hamrlik won't go unclaimed, as a number of teams are looking for depth on the blueline.
