As one of the top offensive lineman available, Stanford tackle Andrus Peat is a projected first-round pick in the 2015 draft, but there’s one catch — he hasn’t officially declared yet. However, multiple sources tell Rand Getlin of Yahoo! Sports (Twitter link) that the junior is expected to enter the draft, so we’ll probably hear an announcement before the January 15 deadline. Here’s more updates on NCAA underclassmen…

• Like Peat, fellow offensive lineman Ronnie Staley hasn’t yet declared for the draft, and he remains truly undecided, per Getlin (via Twitter). The Notre Dame product would rank as the No. 1 OT in the draft, according to Josh Norris of Rotoworld.
• Rice defensive lineman Christian Covington has declared for the 2015 draft, according to Joe Schad of ESPN (Twitter link). Covington, who underwent knee surgery in November, is the seventh-rated DT on CBSSports.com’s rankings.
• Penn State tight end Jesse James will forgo his senior season and enter the 2015 draft, according to a press release. James holds the record for touchdown catches by a Nittany Lion TE.
• Announcing the news himself via Twitter, Florida offensive tackle D.J. Humphries revealed he’ll skip his senior season and enter the draft. A highly-sought after high school player, Humphries had trouble staying healthy in Gainesville, and is rated as the 20th overall tackle per WalterFootball.com.
• Washington State defensive end Xavier Cooper told CougFan.com that he’ll enter the 2015 draft. Cooper, a three-year starter who racked up five sacks last season, said he expects to be a third- or fourth-round pick.
• Kansas receiver Nigel King has declared for the 2015 draft, the school announced via press release. King, who caught 29 balls for 518 yards in 2014, could go undrafted, as he isn’t ranked on CBSSports.com’s list of the top 150 WRs.
