Fredricks out 4-6 weeks, reinforcements on the way, camp cuts. Update.

Bad news for defenseman Jason Fredricks, who will miss 4 to 6 weeks with a knee injury sustained in practice Sunday. Fredricks was one of only four defensemen on the ice to begin camp; Chad Starling is dealing with an immigration issue, Adrian van de Mosselaer is recovering from mononucleosis, and two other signed defensemen are still in the Manchester Monarchs’ training camp.

Fredricks’ injury briefly left the Reign with three defensemen. With the first exhibition game looming Saturday, head coach Jason Christie signed defenseman Jeff MacPhee (no relation to defenseman Iain McPhee) to a pro tryout contract. MacPhee, 26, appeared in four games with the Bloomington PrairieThunder last season after spending most of the year in the Southern Professional Hockey League.

Christie said he’s also signed Travis Gawryletz, a fourth-year pro who is still in camp with the Monarchs. That makes two defensemen hung up in Manchester, along with Jordan Hill.

Update: The Monarchs announced that they’ve cut Gawryletz, so he should be en route to Ontario soon. The 25-year-old spent the majority of the last two seasons in the AHL with Lake Erie; last season he put up four goals, 18 points and 46 penalty minutes in 69 games. He has size (6-2, 200) and the distinction of being drafted in the now-nonexistent eighth round (253rd overall) of the NHL Entry Draft in 2004 by Philadelphia — ahead of Pekka Rinne (258), Mark Streit (262) and Luke Beaverson (283), but behind Alex Ovechkin (1), Yutaka Fukufuji (238) and Dusty Collins (163).

There were two new arrivals at camp Tuesday.

Right wing J.D. Watt amassed an impressive 86 penalty minutes in only 37 games last season between the Abbotsford Heat and San Antonio Rampage of the AHL. Watt was in Manchester on a tryout. In his last full AHL season, 2009-10, the 24-year-old had 267 penalty minutes in 70 games, along with eight goals and 13 points.

Watt played 18 games for the Las Vegas Wranglers in 2008-09 and one game for the Utah Grizzlies in 2009-10, but has otherwise spent his entire three-year professional career in the AHL. Listed at 6-foot-2, 196 pounds, Watt was a fourth-round draft pick (111th overall) by the Calgary Flames in 2005.

Forward Francois Brisebois also joined the Reign after being released from his AHL tryout with the Chicago Wolves. The 23-year-old Montreal native finished a four-year career with Colgate University last season with a 17-goal, 17-assist campaign in 42 games. He also appeared in three regular-season games with the AHL’s Binghamton Senators.

To make room for the new arrivals, three players were cut. Forward Andrew Monesi of Simi Valley and goalie Darren Yount of Alta Loma earned their spots out of the team’s open free agent tryout. Forward Mike Thomson of La Habra Heights was in camp on a pro tryout contract.
