Is there a contradiction in Judas' death in verses Acts 1.18 and Matt. 27.5?

After Judas had betrayed Jesus, the book of Matthew (27:5, KJV) says:
"And he cast down the pieces of silver in the temple, and departed, and went and hanged himself."

The book of Acts says: Acts 1:18 (KJV)
"Now this man purchased a field with the reward of iniquity; and falling headlong, he burst asunder in the midst, and all his bowels gushed out.."

"By comparison with the account in Matthew 27:3-8, it is evident that Judas "purchased" this field only indirectly. He threw down his blood money (the thirty pieces of silver paid him for betraying Jesus) in front of the chief priests, who used it to buy the field called Aceldama (Acts 1:19), or "the field of blood" (Matthew 27:8). He then hanged himself, apparently in the same field, but bungled the attempt, actually dying as described in this verse." source: ("The Defenders Study Bible", pg 1177)
