"WWE Monday Night Raw" is live from Philadelphia with plenty of promotion still to do before "WrestleMania."

Roman's Revenge

Roman Reigns returned last week after being sidelined due to an attack by WWE World Heavyweight Champion Triple H several weeks ago. Reigns came back and attacked Triple H throughout the arena, ending in medical attention for the champion. Expect Reigns to deliver a promo similar to his remarks at the last "SmackDown."

Trouble for Charlotte

WWE Divas Champion Charlotte had her face-to-face-to-face segment with her "WrestleMania" opponents Becky Lynch and Sasha Banks, which led to the challengers attacking the champion in the ring. Charlotte needs to be booked strong in these last couple weeks before the big triple-threat match, and fans should expect her to be on the prowl following the attack on "SmackDown."

Tag-Team Turmoil

WWE Tag Team Champions The New Day officially have their "WrestleMania" match set against The League of Nations. It hasn't been properly confirmed if it will be a standard two-on-two match, since each group has more than two members. It's possible that on Monday the WWE Tag Team Championship match will be confirmed, either as two against two or even three New Day wrestlers against all four League of Nations members.

Also in the tag-team division is the feud between The Dudley Boyz and The Usos, which may still see the addition of Goldust and R-Truth following the events at "SmackDown."

Lana's Unexplained Feud

Lana appears to have the support of Team B.A.D.'s Naomi and Tamina, which may further lead to a match against Brie Bella and Alicia Fox. Lana, however, had a minor confrontation with Paige last "Raw" and even attacked her at "Main Event." Another attack or confrontation against Paige is likely ahead of a potential multi-diva tag-team match. The roles of Summer Rae and even Natalya in this brewing feud will be an interesting element to expect tonight or even at this week's "SmackDown."

"WWE Monday Night Raw" airs weekly on the USA Network at 8 p.m ET.
