Change of plans for BYU's D-Line players?

One of the anticipated strengths of the 2009 BYU defense became a question mark this spring with the announcements that nose tackle Russell Tialavea and defensive end Ian Dulan would serve LDS missions.
While defensive end is still well stocked with talent, Tialavea's departure was a huge concern, with little depth or talent behind him.
Internet rumors have been swirling this week with 1280 The Zone radio host Hans Olsen stating that Tialavea was late putting his papers in and may play this season. Then came a CougarBoard post citing a top BYU defensive player claiming that Tialavea is taking a hard look at putting off his mission and playing this fall.
What gives all of that credibility is head coach Bronco Mendenhall's statements on ESPN's College Football Live program Thursday.
After stating that seven starters return on defense, Mendenhall said this: "Still a few mission plans pending, which at BYU is something you always have to consider. Based on what those plans are, we might need a little but more help at defensive line."
That sounds like Tialavea and possibly Dulan are wavering about the timing of their church service.
Having one or both of them back would be a huge coup for the Cougar defense and BYU's hopes in 2009.
With only one year to play, it would actually make sense for Tialavea to play this year and leave in early 2010 with his career wrapped up. (And maybe with a BCS bowl game to boot.)
Stay tuned to this one.
