U.S. Coach Bob Bradley will reveal the final 23-man roster at 10 a.m. (1 p.m. Eastern) on SportsCenter.

All the players selected for the tournament in South Africa will be on the ESPN campus for the announcement.

From the U.S. Soccer press release:

Tournament rules require that the final 23-man roster be submitted by June 1 to FIFA. A preliminary list of 30 players had to be submitted by May 11 by all 32 teams. According to a new regulation, the 23 players on the final roster must come from the original preliminary roster. Once the rosters are finalized, a team may replace an injured player up to 24 hours prior to their first match of the tournament. In this case, the replacement player does not have to be selected from the 30-man preliminary list.

In other roster news: CRANS-MONTANA, Switzerland (AP) — Algeria midfielder Mourad Meghni will miss the World Cup after failing to recover from a left knee injury.

The Algeria soccer federation says team doctors assessed the 26-year-old Meghni on Monday and decided that he needed surgery.

Meghni, who plays for Lazio in Italy, was one of several players in coach Rabah Saadane’s preliminary squad with dual nationality who played youth internationals for France but switched allegiance after FIFA removed the age restriction last year.

Algeria will play England, the United States on June 23 and Slovenia in Group C.
