The following statement is from WWE.com:
Earlier tonight, Paul Heyman - the former General Manager of SmackDown! - was drafted by RAW and subsequently quit. Therefore, due to the absence of a GM on SmackDown!, I have extended the trading deadline to 9 p.m. ET Tuesday, at which time a new GM of SmackDown! will be announced, and that new GM of SmackDown! will in fact announce all trades. Thank you.
